How it works

Host, invite, play

Step 1

Host a private battle

Tap Host. We create a room that only your friend can enter.

Step 2

Invite by link or code

Copy the link or the six-character code and send it however you like.

Step 3

Play, straight-faced

Once you’re both ready, the round starts. First to break a smile loses a point.

Why Smile Battle

Private, friend-first, quick

Private by default

No random strangers. Every room is invite-only, with a friend you chose.

Two minutes to play

No lobby to browse, no waiting room to sit in — host or join and you’re in.

Free to play

Smile Battle doesn’t charge to host or join a battle.

Safety

Adult-only, and built to be reported

Smile Battle is for adults. Hosting or joining a battle requires confirming you’re 18 or older and accepting our current policies.

Every room is between you and someone you invited — never a stranger. Report and block are available from inside a battle at any time.
